One R5F cluster (MCU_R5FSS0) is present within the MCU domain, and the remaining three clusters are present in the MAIN domain (MAIN_R5FSS0, MAIN_R5FSS1 & MAIN_R5FSS2). The functionality of the R5FSS is same as the R5FSS functionality on earlier K3 platform device J721S2. Each of the R5FSS can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. These subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). There are some IP integration differences from standard Arm R5 clusters such as the absence of an ACP port, presence of an additional TI-specific Region Address Translater (RAT) module for translating 32-bit CPU addresses into larger system bus addresses etc. Add the DT nodes for the R5F cluster/subsystems, the two R5F cores are each added as child nodes to the corresponding cluster node. The clusters are configured to run in LockStep mode by default, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes. The following firmware names are used by default for these cores, and can be overridden in a board dts file if needed: MAIN R5FSS0 Core0: j784s4-main-r5f0_0-fw (both in LockStep and Split modes) MAIN R5FSS0 Core1: j784s4-main-r5f0_1-fw (needed only in Split mode) MAIN R5FSS1 Core0: j784s4-main-r5f1_0-fw (both in LockStep and Split modes) MAIN R5FSS1 Core1: j784s4-main-r5f1_1-fw (needed only in Split mode) MAIN R5FSS2 Core0: j784s4-main-r5f2_0-fw (both in LockStep and Split modes) MAIN R5FSS2 Core1: j784s4-main-r5f2_1-fw (needed only in Split mode) MCU R5FSS0 Core0: j784s4-mcu-r5f0_0-fw (needed only in Split mode) MCU R5FSS0 Core1: j784s4-mcu-r5f0_1-fw (needed only in Split mode) Signed-off-by: Hari Nagalla --- arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi | 120 ++++++++++++++++++ .../boot/dts/ti/k3-j784s4-mcu-wakeup.dtsi | 40 ++++++ 2 files changed, 160 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi b/arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi index e9169eb358c1..3c785cef4f20 100644 --- a/arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi @@ -1112,4 +1112,124 @@ main_spi7: spi@2170000 { clocks = <&k3_clks 383 1>;
